The average price of a gallon of gasoline in missouri was $3.12 (as of 10-2-13 according to the aaa daily fuel gauge report). suppose it is known that . what is the probability that a sample of 60 gas stations taken that same week will have a sample mean within $0.08 of the population mean? (hint: you may need to use as many as 4+ decimal places in your computations to come up with the correct answer! )

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
